Nurse-Led Animated Video Nutrition Education and Its Effects on Dietary Knowledge and Fluid–Diet Adherence in Hemodialysis Patients: A Difference-in-Differences Analysis
Inadequate nutritional knowledge among hemodialysis (HD) patients can lead to poor fluid and dietary adherence, increasing the risk of complications. This study aimed to evaluate the effects of a nurse-led, animated video-based nutrition education program on dietary knowledge and fluid–diet adherence in individuals receiving HD. This experimental study employed a pretest–posttest control group design and included 107 HD patients, 48 in the intervention group and 59 in the control group. Data were collected using a patient information form, a nutritional knowledge survey, and the Dialysis Diet and Fluid Non-Adherence Questionnaire. Descriptive statistics and initial data entry were conducted using SPSS 24.0. The difference-in-differences (DiD) analysis was performed in Stata 18.0. The intervention group received nurse-led nutrition education supported by a 10-min animated video. Measurements were taken at baseline and 12 weeks after the intervention. There were no significant differences between groups in baseline nutritional knowledge or fluid–diet adherence scores. However, at week 12, the intervention group demonstrated a significant increase in nutritional knowledge and a decrease in fluid–diet nonadherence compared to the control group (p < .05). A DiD analysis revealed that the educational intervention resulted in a 4.4-point increase in knowledge scores, which was statistically significant (p < .05). Nurse-led animated video education significantly improved nutritional knowledge and fluid–diet adherence among HD patients. This approach may be an effective tool for supporting patient education and self-management of chronic kidney disease.
